A mains electricity (AC-powered) device designed to facilitate the accurate and consistent administration of drugs and solutions which can be delivered via intravenous, subcutaneous, arterial, epidural, and intracavital routes using a dedicated infusion set. It is used to supply higher pressures than those provided by manually clamped gravity infusion sets or infusion controllers. The device has a typical flow range of 1 to 999 ml/hour and delivers solutions from a standard infusion bag or bottle of fluid. It typically has internal batteries that enable operation for a short period when no mains electricity is available (e.g., during transportation or a power outage).
